The Tho'lein, a proud race that wins the respect, admiration and loyalty of their people through strength and prowess. Any one member of their species, male or female may ascend to a ruling throne so long as they prove themselves in battle or hunting a great beast but either task must be won with honor. A cheat or murderer will just as likely be torn apart by the very people he is attempting to sway to his banner.
Once a King (or Queen) is 'crowned', a chain of golden coins is threaded through the hard, bone protrusions that wrap around a Tho'lein's skull to signify their status.
Humans that have encountered this race sometimes refer to them as Blue Devils due to their skull-like appearance and crown of sharp bone.
for their awesome gallery of stock images, one of which I used as a (very) loose reference point for the pose in this painting.
